Hi.
Just starting to look at how to use jsonb columns and I have a question. I have
found out that I can use the following to search for a value inside
the jsonb column:
select * from orders where info ->> 'customer' = 'John Doe' (where info is
the jsonb column)
But what if the jsonb column contains an json array, how can I search then?
info -> [ { "customer" : "John Doe" } ]
If you know the index in array, you can search like
info->0->>'customer'
If you want to search in any array element, you need to use JSQUERY
extension,
see https://github.com/postgrespro/jsquery
btw, using PostgreSQL 9.6 but will be moving to 10 soon.
